Patented Dec. 26, 1939 UNITED? STATES- ore-ice 7 This invention relatesto hand operated tools especially adapted for removing foreign matterfrom road'surfaces and the joints of concrete roads and the like and hasfor the primary object the provision of a tool of the above statedcharacter whereby'aperson may with ease and quickness condition a roadjoint and road surface for recementing or 'calking whereinit'isessential to have the joint or road surface free of 4 dirt and otherforeign matterbefore the cement or calking material is applied.

Another object of the invention isthe provision of a portable toolholder requiring only minimum effort on the part of the operator-for itsmovement over'a road surface and which is equipped with cutting andscraping tools easily brought into place for use and held against losswhen not in use. p I

With these and other objects. in View. this in- *vention consists incertain nov'el featuresof construction, combination and arrangement ofparts to be hereinafter more fully described and For a completeunderstanding'of my invention,

reference is to be had to the following desoription and accompanyingdrawing, in which Figure 1 is a fragmentary'side-elevation'illus tratinga tool constructed in accordance with the invention.

Figure 5 is a view similar to Figure ishowing a modification of thepresent invention.

Figure 6 is a fragmentary top plan view showing the modification.

Referring in detail to the drawing, the numeral I indicates a body ofthe tool holder and which is of elongated formation and has detachablysecured on one end a handle 2.

Formed on the body I adjacent the other end thereof are pairs ofshoulders or lugs 3 and cooperating with said lugs in gripping a shank 4of a tool is,a clamp 5 consisting of a member 6 to fit between the pairsof lugs and overlie the shank of the tool. Integral withthe member 6 areoppositely arranged apertured ears I through which bolts or likefasteners 8 extend.- The fasteners 8 are secured in the body I. Thepairs of lugs 3 and the member 6 cooperate in removably securing thetool on the holder orbody l and against "rlat movement thereto'du'ring aclean ing-operatiohZ-- The tools may be of various kinds a'nd shapesome" of which are to operate in a road j oint 'for the p'urpose'ofscraping or cutting therefrom dirt and otherforeign matter accumulatedin the jointso as to prepare' 'the joint to be recementd' or- 'calkediOne of the tools'is in the form ofa' blad'e 9 and having a'shank l0secured thereto. The blade 9' is 'ofaselected Width having' scraping orcutting edge presented for-movement over asurface' ofa road-to scrapetherefrom-foreign niatten'ashoivn in Figure 1. The tools whei'inot inuse are removably mounted on the body l-by a clamp II. Asubstanti'allyU- shaped member l2'is'p'ivota1ly mounted on the body-l it adj acentthesecuring lugs '3 and has integral'thereu ith spaced 1egs 13 on'whicharejournald rollers" l4 to'ride'the'surface of a road duringeitherthe-cutting or' scr'aping' operation.

Formed' on the U-shaped-member IZ -an'd extending upwardly therefromisanj arm [5 to pivoted a flexiblerod" I6 one end'ofwhich is" disposedangularl'y thereto to" enter any onefof' a series-"of socket's' l'lfrm'e'din the'body. Said eiid of the'ro'd maybe readily moved from onesomer-toanotherfo'r adjust-ingthe cutting action 'of' th'e blade 1necessary for different joints in'a'-'roadway:- Tl'ie rod adjacent thelatternamed end' iscoildto give desired resiliency to said-rod; Securedto the rod I6 is a coil spring l8 and the latter is secured on the bodyI and acts to urge the rod I 6 in the direction of the body to retainone of its ends in engagement with a socket.

The legs I3 move relative to the body I in accordance with the amount ofmanual pressure placed on the body. Thesubstantial normal position ofthe legs I3 is as shown in Figure 1 so as to position the rollers M in aplane slightly below the tool carried by the body so that the rollersmay move over a surface with the tool in engagement with the surface.However, when cleaning a crack or joint in the roadway additionalmanualforce is applied on the member I causing the legs to swing past andabove the tool as shown in Figure 4, still contacting the surface of theroadway with the tool extending fully into the crack or jointso that asthe device is moved along the crack or joint foreign matter will be cut,scraped or otherwise removed from the crack or joint. v

Referring to my modified form of invention a tool holder I9 is providedwhich consists of a member 20 having a shank 2! extending upwardly fromone end. The shank 21 is secured on the body I by the clamp 5 and lugs3. When the body I is disposed in an operating position with the rollersin engagement with the surface of the road the member 20 is disposedsubstan tially horizontally to the surface of the roadway and haspivoted to its forward end an arm 22. A coil spring 23 is connected tothe member 20 and to the arm 22 urging the latter downwardly toward themember 2!. The member 2| is of a bifurcated construction through which atool 24 may extend. The tool is carried by the arm 22.; The cutting endof the tool when so mounted on the body 5 is disposed in a plane belowthe rollers for operation in a crack or joint of a roadway and iscapable of yielding upwardly if engaged and extending forwardly anddownwardly on opposite sides of the body and the tool carried thereby,rollers journaled on said legs to ride the surface of the road, an armintegral with said U-shaped member and extending upwardly and forwardlywith respect to the body, said body having a series of openings, aresilient rod pivoted to said arm and adapted to have an end thereofinsertible in any one of the sockets.

2. A device for preparing road joints and road surfaces comprising abody, a handle for said body, means for detachably mounting on said bodydifferent types of tools, means on said body for supporting said toolswhen not in use, a substantially U-shaped member pivoted on. said body,legs integral with said U-shaped member and extending forwardly anddownwardly on opposite sides of the body and the tool carried thereby,rollers 'journaled on said legs to ride the surface of the road, an armintegral with said U-shaped member and extending upwardly and forwardlywith respect to the body, said body having a series of openings, aresilient rod pivoted to said arm and adapted to have an end thereofinsertible in any one of the sockets, and

a coil spring connected to said rod and to said body and acting to urgethe rod toward the body.

ing means carried by said body, rollers yieldablyand pivotally mountedon said body to engage with a surface, a shank secured on said body bythe clamp and extending forwardly thereof in a plane parallel with thesaid surface supporting the rollers, an arm pivoted to the shank, a toolcarried by the said arm, and resilient means co- .acting with the tooland the said shank to yieldably support the tool in a working positionand a tool carried by said shank.

, 4. A device for preparing road surfaces and joints comprising anelongated body, a handle connected to one end of said body, clampingmeans carried by said body adjacent the other end thereof, rollersyieldably and pivotally mounted on said body to engage with a surface,

a shank secured on said body by the clamp and extending forwardlythereof, a member integral with said shank and extending forwardlythereof and in a plane substantially paralleling a plane of the surfacesupporting said rollers, an arm pivoted on said member and extendingupwardly and rearwardly in the direction of the body, a toolcarried bysaid arm and having its work end disposed below said member, and aspring connecting the arm and member to yieldably support the tool in aworking position.

5. A. device comprising an elongated body, having a plurality ofopenings, a bracket pivoted to the body, rollers journaled to the saidbracket, and a resilient rod having one end pivotally attached to thebracket and adapted to have the other end thereof inserted in any of thesaid openings.

6. .A, device comprising an elongated body, having a plurality ofopenings, a bracket pivoted tothe body, rollers journaled to the saidbracket, aresilient rod having one end pivotally attached tothe bracketand adapted to have the other end thereof inserted in any of the saidopenings, and a tool detachably secured to the said body having thepositioning'of the working end thereof controlled by selectivelypositioning the end of the resilient rod in various of the saidopenings.
